Description
Technical field
The utility model relates to a kind of monitoring instrument, is that a kind of tension force and micrometer show convergence gauge totally.
Background technology
Convergence gauge utilizes the method for mechanical transfer displacement when measuring, the relative displacement between two reference points is changed into twice difference of reading of displacement numerical value.Give the steel tape constant-tension with spring, the equal conditions when guaranteeing to measure.
The convergence gauge that home products adopts is mechanical drive mostly, utilizes dial gauge to show displacement result, exists poor sealing performance, uses very easily in the rugged surroundings of tunnel and damages, and reading is not directly perceived, easily misreads shortcomings such as dial gauge spoilage height.Existing digital display type convergence gauge can only show the change in displacement value, and the tension force demonstration is also just distinguished tension variations by the mechanical type scale, and error is big, occurs the disappearance of rock deformation easily in measurement.Read-around ratio is difficult under dark surrounds.
Summary of the invention
The purpose of this utility model is to provide a kind of tension force and micrometer to show convergence gauge for overcoming above-mentioned deficiency totally.The measuring accuracy height, easy to use.Convergence gauge reading of steel tape tension force and displacement when detecting can show by electronics; And under dark surrounds, can throw light on and make things convenient for reading numerical values.
The purpose of this utility model is achieved in that a kind of tension force and micrometer show convergence gauge totally, comprise hook, setting nut, displacement mechanism, displacement display device, lighting device, tension force display device, shell, tension mechanism, chi card, steel tape, chi frame, rocking handle.Steel tape is fixed on the chi frame, and setting nut is connected with shell.Be respectively equipped with hook at steel tape head and shell one end.Be provided with lighting device in the shell, lighting device is installed in by tension mechanism and the displacement mechanism.
Shell is provided with tension mechanism and displacement mechanism,
Described displacement display device is installed on the shell medial surface by displacement mechanism, and the other end links to each other with shell.Described tension force display device is installed in the enclosure by tension mechanism, and the other end links to each other with shell.
Described setting nut is connected with displacement mechanism, can drive the displacement mechanism parts and move.
Tension force and displacement readings can directly show on display device, and be numeral and show that be convenient to observation, precision also is improved.The user can solve the bad control of tension force in the past and show coarse problem the directly control of tension force size like this.Numerical value is surveyed the problem of reading in the lighting device change dark surrounds.
Description of drawings
Fig. 1 is that tension force and micrometer show the convergence gauge synoptic diagram totally;
Fig. 2 is that tension force and micrometer show convergence gauge use synoptic diagram totally;
Embodiment
Further specify the utility model below in conjunction with drawings and Examples.
Tension force and micrometer show convergence gauge totally and are made up of hook 1, setting nut 2, displacement mechanism 3, displacement display device 4, lighting device 5, tension force display device 6, shell 7, tension mechanism 8, chi card 9, steel tape 10, chi frame 11, rocking handle 12.Referring to Fig. 1.Steel tape is fixed on the chi frame, and the chi frame is connected with setting nut.On steel tape head and shell, be respectively equipped with hook.Steel tape is provided with pilot hole.
Be provided with tension mechanism and displacement mechanism in the shell.
During use, elder generation's pre-buried good two ends measuring point 13, measuring point is provided with the spherical hinge structure of scalable direction, shaking rocking handle launches steel tape and makes that hook links to each other with the ring of a measuring point on the steel tape, encircle and be connected with on hook on the convergence gauge shell and another measuring point, select suitable pilot hole, chi hole pin is inserted pilot hole, steel tape is fixed under the effect of chi card.Referring to Fig. 2.Give the steel tape constant-tension with the spring in the tension mechanism, the equal conditions when guaranteeing to measure.The tension force coarse adjustment can and be positioned the latch on the convergence gauge device for measuring force to realize in the suitable perforation of steel tape by the tension steel tape.The tension force fine tuning can be finely tuned tension force by setting nut, and promptly spring base drives the capacitor grid transducer chi, and shows numerical value.Under the effect of identical springs pulling force, steel tape tightens up, and high-precision displacement display device can be measured the fine tuning value.The used capacitor grid transducer of displacement mechanism and tension mechanism is a shaped article.Write down the steel tape reading, add (or deducting) micrometer fine tuning reading, can obtain the measuring point displacement value.As the light darkness, can open lighting device and give the luminous demonstration reading that illuminates.
Utilize two relative displacements between reference point to change twice difference of reading of displacement numerical value into when convergence gauge measures like this.After the use, in time the backward rotation setting nut takes off steel tape from measuring point, takes off convergence gauge, and the reverse rotation rocking handle is recovered to the chi frame to reference position with steel tape.
